The type-bars in standing upright upon its rear end; Fig. 2", the instance shown are provided each with two type and are pivoted near their lower ends upon type-bar hangers K, which are suitably secured at the upper side of a sectorshaped frame L, secured at its opposite ends in the main frame of the machine. The typebars are connected by wires M with their respective key-levers A and are normally held against the type bar rest V by means of springs R, con uected at their ends to the type-bars and to ears Q, connected with the frame L.

The construction, arrangement, and other features relating to the type mechanism herein shown and above referred to form the subject-matter of the claims of a divisional application filed April l0, 1899, Serial No. 712,476.

When in normal position, the type-bars rest at their outer sides against a curved type-bar rest V, supported at its opposite ends upon the end of the frame L by lneans of downwardly-extending arms W. The shaft B, on which the key-levers Aare journaled, is suitably mounted in lugs or brackets D, attached to the frame of the machine.

The paper-carriage is mounted upon a backwardly and forwardly shiftable plate or frame X, Figs. l, 2, 3, 4, 6, and 7. The manner of supporting this plate X upon the main frame of the machine is best shown in Figs. 5 and 6, where it will be seen that the opposite side plates of the frame of the machine have secured to them two bars Y Y, provided with V-shaped grooves along their inner sides, while the plate X has secured to its under side adjacent the respective bars Y Y two similar bars Z Z, provided upon their outer sides with V-shaped grooves corresponding to those in the bars Y Y, while fitting between said grooves are balls Z'. The adjustment of the parts is such that the plate X is entirely supported upon the balls and the friction between it and the frame of the machine thereby relieved.

The purpose of shifting the frame X forward and backward is to move the platen carried thereby from the position in which the lower-case letters and other characters are printed by one set of the double-case type on the type-bars to the position in which the upper-case letters and other characters are printed by the other set of type on the bars.

As heretofore stated, the backward and forward movements of the paper-carriage are controlled by the upper-case key H. This is secured to the front end of a lever A', which is fulcrumed at the extreme rear end of the machine at the left-hand end of the fulcrumrod B of the main key-levers, Figs. 2 and 3. The lever A' has connected to it the horizontal arm of a bell-crank lever B', Figs. 2 and 3, hung upon a stud projecting inward from the side frame of the machine and whose upper end bears against the forward edge of the frame X, orin this particularinstance against the front end of the left-hand bar Z, secured to the side of said frame, as heretofore. When the key l-I is depressed, the upper end of the bell-crank is thrown rearward and the frame X and parts carried by it moved in that direction, and when the key is released the parts will be returned to forward position by a coiled spring C', Fig. 2, connected at its rear end to the frame X and at its forward end to a fixed part of the framework.

For the purpose of holding the frame X and paper-carriage in rearward position when desired there is provided a crank A, Fig. 3, journaled in the side frame of the machine and having upon its inner end a short arm adapted to bear upon the upper edge of the lower arm of the bell-crank B'. By swinging the lower end of the crank-handle upward and forward the lower arm of the bell-crank may be depressed and the frame X thrown rearward and held in such position as longas desired by the engagement of the arm of the crank with the bell-crank.

'lhe frame X is limited in its backward and forward movement by the stop devices shown in Figs. 2 and 2, where D' represents a bar firmly secured to the under side of the rear top plate of the main frame of the machine and extending forwardly therefrom and provided with a longitudinal slot E'. Located upon the upper side of the bar D' are two adjust-able stops F F', provided upon their under side with lugs fitting in the slot E'. Screws G', passed through the slot E' from the under side of the bar D and entering the stops F' F' or the lugs thereof and having washers H' interposed between their heads and the under side of the bar D', serve to hold the stops F' F' in fixed position upon the bar D', but also permit the necessary adjustment of them. Secured to or formed upon the under side of the frame X is a block l', which fits and has play between the stops F' F' upon the upper side of the bar D', the contact of which block with said stops limits the backward and forward movements of said frame.

The laterallymovable paper -carriage is mounted upon the upper side of the backwardly and forwardly shiftable frame X near its forward end in the following manner: Supported upon the frame X by means of four brackets J', two being located near the opposite sides of the frame, Fig. 7, are two transverse bars or guide-rails K' K', the rear one of which is provided upon its forward side and the forward one upon its rear side with a V-shaped groove, Fig. 4. The main frame of the laterally-movable paper-carriage is composed of a bottom plate or bar L', Figs. 4 and 7, and two vertical side or end plates M' N', secured to the opposite ends of the plate L'. The latter plate iits between the two bars K' K' above described, Figs. 4 and 7, and is provided upon its front and rear edges with V- shaped grooves opposite those in the bars K', and balls O' are interposed between the front and rear edges of the plate L' and the respective bars K' and serve to support the papercarriage upon said bars and relieve the fricl milled thumb-pieces Q'Q', by Which it may R', whose spindle is supported at its opposite ends in bearings S', projecting from the frontv edge of the paper shelf or table T', Fig. '4,

which extends beneath and to the reary of the platen-roller Gand serves Ato guide the paper This paper-` as it is inserted in the machine". shelf T' has projecting -frmlits,opposit'en'ds short spindles U', Figs. 4 and 5, journaled in the respective end plates M N' of the papercarri'age, so that the paper-shelf and the pressure-roller R', carried by it, are freeto rock upon their support. Flat springs V', secured at theirl rear; ends to thef bottom plate L' of, the paper-carriage, 'press' vupwardly at their forward ends against the under sides of .the bearings S', in which the opposite ends of the spindle of the roller R' are carrie'd,and serve to press the roller R against the platen-roller. This pressure of the rollerR' against the roller G may be relieved and the roller R' thrownk out of contact with the roller G whenever desired by simply pressingupward upon the rear edge of the paper-shelf T". Inthis manner the sheet of paper inserted between the platen-roller and roller R' may be readily released at any time for the purpose of removing or adjusting it. j

The scale of the machine is formed upon a curved plate XV', fitting against the forward side of the platen-roller G, Figs. 1,4, and 5. The plate WV', is secured tothe rear side o f and carried by a rod X', which is mounted at` its oppositeends in short slots o'r elongated openings' in the respective side plates M' N of the' paper-carriage, as shown inFigs. 3, 4, j

and 9. Coiled springs Y' Y', connected to the rod X' at its opposite ends, Fig. l, serve to yieldingly hold the rod in rearward position, with the plate W' fitting against the roller G. The plate W', yieldingly pressed against the platen-roller in this manner, serves to properly direct the paper upward around the 'forward side of the roller and also furnishes a' location `for the scale in front of the printingline. The plate is preferably provided with a series of openings X", through which the lower edge of the sheet of paper may be observed as the writing appoaches the lower end opposite ends in the side plates of the 'papercarriage,`Figs.1,3,`4;5,and'6. Coiledsprings C2, surrounding the rock-shaft B2 at its opposite ends and secured at one end to the shaft and at their oppositev ends to the' side plates of the paper-carriage, tend 4to turn the shaft forwardand serve to yieldingly press the` paper-1ingersfA2against the u pper side ofthe platen-roller. Each of the paper-ngers'A2 is mou'nted'upon' the rock-'shaft B2 by means of vtwo upwardly-bent ears D2, provided with square holes, through whichA thel rock-shaft passes, thus leavingy the fin gers free `to be slid longitudinally along said shaft. pose'of lholdingthe' paper-fingers in the different positions to which they may be adjusted along the shaft B3 each one of said-fingers has'pivoted to'one of itsupwardly-projecting ears vD2 a short arm E2, the pivotal point of the arm being immediately Ibeneath the shaft B2 arid the armA extending rearwardlyandup-l wardly from' its pivotal point to form a handle for manipulating'the arm, as shown in Figs. 1`,` 3, 6, 9,'a'nd lO. As seen in Fig'. 10,

v `8o For the purthe forward end of the arm E2 above its pivot is formed into a cam-surface adapted to -bear against the ,underv surface of the yrock-shaft B2 when the rear end of the arm E2 is thrown upward and forward, and 'thereby serve to lock the paper-,ngerin place on the shaft B2. t,

When it'isdesired to shift the finger longitudinally vof the shaft, it maybe released for that purpose by pressing the'rear end of the' arm E2 downward,andi`thereby disengaging IOO the'cam-s'urface 'of the arm from thelunder surface of the' shaft B2.

The above-described construction and arrangement of partsfurnish a simple and conveulent support for the-paper-tingers and permit them to be readily adjusted laterally to different positionsandfirmly held in such adjusted position. h

The rock-shaft B2 has secured to it in xed position nearits middle two curved fingers F2,

Figs. 1 and 6, 'under which the 'middle porv tion of Athe sheet of paper passes and which serve tohold such portion of the paper in .proper'position during its movement beneath them.V

The platen-roller is turned rearwardin the regular operation ofthe machine to space the lines by means of a ratchet-and-pawl mechanism at its left-hand end, which may be next i described. vThe roller has secured to its lefthand end an annular ratchet G2, Figs. 1V, 5,6, y and 9, with which coperates a pawl H2, mount- IIS,

IZO

vthe bottom plate L' of the paper-carriage and passing at its outer end thro ugh the left-hand side plate N' of said carriage, and having secured to and projecting upward from its ex-` treme outer end a lever or handle K2, shapedk at its upper end to form a linger-piece L2 for ,convenience of manipulation. A coiled spring M2, surrounding the shaft I2 between the plate N' and lever K2, Fig. G, and secured at one end to said plate and at its opposite end to the shaft or to the hub of the lever K2, tends to turn the shaft I2 rearward and servos to yieldingly hold the pawl H2 and lever K2 in their normal rearward positions, the rearward movement of the parts under the .stress of the spring M2 being limited by contact of the upper end of the pawl H2 with a screw N2, projecting inward from the plate N', Figs. 6, 8, and 9.

The pawl H2 is not mounted rigidly or directly upon the rock-shaft [2, but, as seen in Figs. S, 9, and 13, is pivotally mounted upon an arm O2, rigidly secured upon the shaft, the lower portion of the body of the pawl being forked to straddle and embrace said arm. The upper end of the pawl H2 is pressed in* ward (to the left in Fig. 6) by means of a wire spring P2, secured at its lower end to the outer side of the arm O2, Fig. 9, and bearing at its upper end against the outer side of the upper end of the pawl. The stress of this spring tends to throw the upper end of the pawl into engagement with the ratchet G2 of the platen-v roller; but when the parts are in their normal rearward position the upper end of the pawl is held away from the ratchet by engagement with the beveled head of the screw N2, the head of this screw operating as a cam to throw the upper end off the pawl outward away from the ratchet as the pawl returns to its normal rearward position under the action ot the spring M2, as heretofore described. Vhen, however, .the upper end of the lever K2 is pulled forward and the upper end of the pawl H2 carried away from the screw N2, the spring P2 will throw the upper end of the pawl inward into engagement with the ratchet G2 upon the platen-roller and the pawl be thereby caused to carry said roller with it during its forward movement imparted by the lever K2. The forward throw of the lever K2 is limited by contact of the upper end of the pawl H2 with an adjustable stop Q2. (Shown in Fig. 8.) This stop Q2 consists of a stud projecting inward from the lower end of a plate R2, hung at its upper end upon the spindle of the platen-roller and pressed against the inner face of the end plate N' of the paper-carriage by means of a coiled spring S2, surrounding the spindle of the roller and con- [ined between the end of the roller and the plate N' of the paper-carriage, Figs. 5 and G. The plate R2 has projecting forwardly from it an arm or extension T2, provided with a knob or handle U2, Figs. l, 3, 5, 8, and 9, by

' means of which the plate may be swung backdifferent adjusted positions. There are in the present instance three notchesl in the plate N', so that the plate R2 and stop Q2 may be held in any one of three different positions, the stop being held in rear-most position when the lug V2 is engaged with the lowermost notch W2, in middle position when engaged with the middle notch, and in forward position when engaged with the upper notch. The inner end of the stud or stop Q2 is rounded or beveled to coperate with the upper end of the pawl H2, which latter is of the shape best shown in Fig. 13. Vhen in its forward throw the upper end of the pawl H2 contacts with the inner end of the stop Q2, the pawl will be wedged by the beveled end of the stop into the particular notch of the ratchet with which the pawl is engaged, and the engage ment of the pawl with the stop thus not only serves to arrest the pawl, but to lock the pawl in engagement with the ratchet, and thereby also positively arrest the movement of the ratchet and roller and prevent them being overthrown by any quick or violent manipulation of the lever K2. The adjustment of the parts is such that when the stop Q2 is in its rearward position it will serve to arrest the pawl and platen-roller when the latter has been turned the space of one notch or tooth of the ratchet. Vhen the stop is in its middle position, it will permit the roller to be turned the space of two notches, and when in forwardposition it will permit it to be turned the space of three notches. In this manner the parts may be readily adjusted to space the lines either one, two, or three units of distance apart.

It will be understood from the foregoing that the pawl H2 isl normally entirely disen gaged from the ratchet of the platen-roller, and the latter is free to be turned forward and backward by means of the milled thumbpieces upon the opposite ends of its spindle. For the purpose of yieldingly holding the platen-roller in any position to which it may be so turned and also to enable it to be readily moved backward and forward the exact distance necessary to bring any desired line of written matter to the printing-lino the ratchet G2 upon the lefthand end of the roller is engaged by a roller X2, Figs. l, 3, 5, 6, and 9, which is mounted upon a stud carried by the inwardly-bent horizontal upper end of a spring-plate Y2. This plate Y2, as shown in Fig. 3, is secured at its extreme lower end to the outer side of the end plate N' of the papercarriage and is provided near its middle with a hole through which the spindle of the platenroller passes and at its upper end is bent inwardly to horizontal position and iits in a vertical slot cut in the upper edge of the plate N', as shown in Figs. l and 8. The size of tho roller X2 is such that the teeth of the ratchet G2 may freely ride over it in either direction as the platen-roller is turned backward or forward; but at the same time the engagement of the roller with the notches of the ratchet IOO IIO

, positions corresponding to the several notches when thelever is lpulledforward to pass `be- 4ratchet' by the lever Z2, as heretofore expointer with the-minor divisions of the scale serves to always arrest and yieldingly hold the roller in one or another of the dierent of the ratchet.

For thepurpose of diseugagiug the roller X2 from the ratchet wheneverdesired and holding it disengaged therefrom to permit the platen-.- roller to be turned backward or forward with. still greaterease and to permit it to be arrested, if desired, in a position intermediate th ose determined by the notches ofthe ratchet when the roller is engaged bythe latter there is provided a diseugaging-lever Z2, Fig. 3, pivoted at its lower end to the plate N ofthe papercarriage and formed at its upper end into a suitable finger-piece and provided upon its forward side with an arm ortinger adapted tween the spring-plate Y2 and the plate N of the paper-carriage and force the plate Y2 outward, and therebycarry the rollerv X2 away from the ratchet of the platen-roller. rlhe rollerwill be held in this disengaged position until the lever Z2 is` again pressed rearward to normal position, in which position it is arrested bycontact with a stopprojecting from the plate N, as seen in Fig. 3.

As shown inFigs. 1, 5and 6, the platenroller G is provided around its right-hand end with a series of graduations, withwhich cooperates a pointer A2, secured tothe end plate M of the paper-carriage. y The main divisions on this scale upon the platen-roller correspond to the notches in the ratchet upon the opposite end of the roller, so that when the roller is in any one of -what may be termed its normal positions (determined by the engagement of the roller X2 with the notches of its ratchet, as heretofore explained) oneof the main division-lines of the scale will stand opposite the pointer.4 When, however, the roller X2 is held out of engagement with the plained, and it is desired to turn the platenroller to position intermediate those positions determined by the engagement of the roller X2 with its ratchet, the coperation of the upon the platen-roller may be advantageously employed for adjusting the platen-roller to the exact position desired. y

The escapement mechanism and coperating parts will` be next described, reference being had more particularly to Figs.y6, 7, and 12. r The escapement bar or rack A2 is-supported at its opposite endsby side arms B2 C2, pivoted at their forward ends to the outer sides of the end frames M N.' of the papercarriage, Figs. 3, 6,. and 8, the side arm C2 at the left-hand side of the machine being exwardly-curved arm D2, provided with a button at its upper end, Figs. 3 and 8, for apurpose hereinafter described. At its opposite ends the Vrack-bar A2 fits in recesses E2 in the rear edges of the end ,frames ofthe paper-carriage, t-he upper and lower walls of whichremight, asshown in they drawings. I cent ends of the two sleeves are ,counterbored cesses limit the vertical play of the bar.` A spring suitably applied to the bar at one end, but not shown, aids gravity in yieldingly holding it in andreturning it to its lower norcarriage at itsx right-hand end, is shown in y Fig. 6. As also vshownin said figure and also in Figs. 7 and. l2, there are secured upon the upper sideof the barvKQ'heretofore described,

two lugs H2 H2, between which is mounted a rock shaft I2, engaged andsupport-ed at its opposite ends by centering-points upon the inner ends of screws J2, passed through said lugs. An arm K2, projecting rearwardly fromits rock-shaft, has connected to its rea-r end the upper end of a link L2, whose lower en d is connected to the universal bar or rod M2, forming partofa bail composed of said rod and two side arms N2 N2, Fig. 2, said side arms being hung at their rear end upon the fulcrum-rod BV of the key-levers. The rod M2immediatelyunderlies all of the key-levers A, as shown in Figs. 2 and 4, and also the side arms O2 O2of the spacing-bar P2 and .is yieldingly heldin and, returned to upper-position by a coiled spring Q2, Figs. 4 and 6. At each depression Vof the front end of a key-lever oi of thespaoing-bar, therefore, the rock-shaft l2 will be rockedrearward. Mounted upon this rockshaft l2 are two escapementpallets, each consisting ofa sleeve surrounding the shaft and having a sector-shaped wing `or angeprojecting fromit. The right-hand one, R2-,of these two pallets, Figs. 6,7, and 12, is fast upon the rock-shaft I2, while the left-hand one, S2, is splined uponthe shaft, so as to turn with the shaft,.but slide thereon, its movement to the right beinglimited by the sleeve ofthe pallet R2 and in the opposite directionby a collar T2, fast upon the shaft ,near its left- `handr end. As shown in Figs. 7.andl2, the

adjacent ends of the sleeves of thesetwo p allets are so cut away that the ends-ofthe sleeves may pass each other and allow the two pallets R2 S2 to stand in the samevertical plane witheach other circumferentially .of the shaft when the pallet S2 is moved to the The adjaand have interposed between them-a coiled spring U2, (shown in Fig. 12,) which tends to vpress the pallet S2 to the left and contact the end of its sleeve with the stop-collar T2.

`Under the above construction and arrangement of the parts the operation is as follows:

In normal position of rest the pallet R2 stands forward `of the rack A2 and out of engage.

ment therewith, Fig. 6, while thepalletS2, is engaged with a tooth of the raclc and serves to hold it from movement toward the-right under the stress of the paper-carriage spring.

vThe action of this spring overcomes. there- IOC IIO

sistanceof the coiled aspring U2, interposed between the two pallets, and the pallet S3 is held in right-hand position (referring to the drawings) in the same vertical plane as the pallet R3. When the front end of a key-lever or the spacing-bar is depressed andthe shaft I3 rocked rearward, as above described, the pallet S3 will be carried rearward out of engagement with the tooth of the rack, while the pallet R3 will at the same time be carried into the path of said tooth and serve to hold the rack-bar and paper-carriage from movement. Immediately upon its disengagement from the tooth of the rack-bar the pallet S3 will be thrown to the leftby the coiled spring U3 until its sleeve contacts with the collar T3, bringing it opposite the next succeeding notch in the rack-bar. When the operated key-lever or the spacing-bar is now released and the rockshaft 13 turned forward to normal position by the action of the spring Q3 upon the universal rod M3, the pallet R3 will be carried forward out of engagement with the first-mentioned tooth of the rack, while the pallet S3 will be carried into the path of the succeeding tooth, and as soon as the rack-baris released by the disengagement of the pallet R3 from the firstmentioned tooth the paper-carriage spring will move the paper-carriage and rack-bar t0 the right, carrying the pallet S3 with them, until they are arrested by the contact of the sleeve of the pallet S3 with the sleeve of the pallet R3, as shown in Fig. 6. At each depression and release of the key-lever or the spacing-bar the paper-carriage is thus permitted to move the distance of one tooth or notch of the rack-bar.

It will be seen that by the employment of escapement-pallets-constructed and arranged as above described I succeed in bringing the points of engagement of the pallets with the teeth of the rack-bar very close to the pivotal axis of the pallets, and thereby reduce to the minimum the power necessary for the operation of the pallets. The construction and arrangement employed are also exceedingly simple and such as to withstand to the highest degree the strain and wear incident to the operation of the machine and reduce to the minimum the necessity for readjustment of ther parts. It will also be seen that the movement of the pallet S3 with the rack-bar is a sliding movement exactly parallel with Vthe movement of the rack-bar and paper-carriage, so that during such movement the pallet and rack-bar remain in the same position relatively to each other, and there is no movement of the one upon or independent of the other, as necessarily occurs where the`move. ment of the pallet with the rack-bar is movement in the arc of a circle, as is the case where such movement of the pallet is on a pivotal axis transverse to the movement of the rackbar.

For the purpose of automatically lifting the rack-bar when the paper-carriage is shifted to right-hand position to begin a new line and prevent the rack-bar dragging over the pallet S3 there is provided at the left of the escape- Vment mechanism in Fig. G an automatic lift- Fig. 6 its teeth slip freely overl the corner of the plate V3,the spring X3 being light and readily yielding for that purpose; but when the paper-carriage is pushed in the reverse direction (to the'left in Fig. 6) the upper corner of the plate V3 locks between the lower end of the two adjacent teeth of the rack, and the pressure of the latter upon it swings it to the leftv upon its pivot, thereby causing its corner engaged with the rack to rise and lift the rack with it. When it has lifted the rack until the upper surface of the plate is brought to horizon tal position beneath the rack, it will be arrested by contact with a stop Y3 upon its support W3, and the rack will then freely travel over its upper surface. Upon the first movement of the paper-carriage in thereverse direction (to the right in Fig. 6) the lifter plate V3 will return to the position shown in said view, and during the continued movement of the paper-carriage in that direction the teeth of the rack will slide freely over the corner-plate, as heretofore described. It will be understood from the foregoingthat the paper-carriage may be freely slid toward the right at any time by simply pushing it in that direction without the necessity of manipulating any device for lifting the rack-bar out of engagement with the pallet or otherwise disengaging them, as is necessary in many machines now in use. When it is desired to slide the paper-carriage to the left independently of the operation of the keys or space-bar, the rack-bar A3 may be readily lifted out of engagement with the pallet S3 to permit such movement by depressing the front end of the lever D3, heretofore described, Figs. 3 and 8.

The gong-sounding devices of the machine, by which the gong A4, Figs. 2, 5, and 6, is sounded as the paper-carriage approaches its limit of movement to the left, may be next described, reference being had to Figs. 4, 5, and 6. The gong-striker is carried by a leverBi, pivoted at C4 to a support depending from the under side of the frame X. Connected to the short arm of this lever above its pivot is a coiled spring D4, extending in "one direction, While connected to the lever near the same point and extending in the opposite direction is a link E4, which serves to connect the striker-lever with a short lever F4, pivoted at its lower end to a support depending from the under side of the frame X and projecting at its upper end through a slot IOO IXO

The plate H4 is adjustably secured upon the rack-bar A3, so that it may be moved longitudinally ,thereof and Vset in different positions to cause the gong to be sounded at different pointsin the travel .of lthe paper-V carriage. Y To this end the plate H4 is secured to the rack-bar in the following manner;v The extreme forward edge ofthe horizontal upper portion ofthe plate is bent downward to vertical position and vfits against the forward side of the rack-bar, Fig. 4.- Securedto the under sideof this horizontal portion at its junction with the vertical rear portion' of the plate is a'short bar or block K4, rectangular in vertical cross-section, which fur-A nishes a 'support Afor av plate L4, which is secured at its rear edge to the under side of` said bar and at its forward edge bears against the under surface of the rear portion of the.

rack-.bar A3, in rear of the teeth of said bar. A screw M4, passed from the under side of the plate L4 through a hole in the latter, enters at its upper end a threaded holein the horizontal top of the plate H4, so, that by tighten-V ing up this screw the rack-bar may be clamped between said plate and the plate .L4.- Interposed between the head of the screw M4 and the under side of the plate L4 is a spring N4, Fig, 4b, bent downward at itsv middle, where it is engaged by the head of the screwand bearing at itsopposite en dsagainst the ,nn. -Theinterpositionot der side of the plate L4.

this spring between the head of the screw and the plate L4 permits the pressure of the forward edge of the plate L4 against the under. side of the rack-bar-A3 to be better regulated by means of the screw and .enables the parts to befrictionally held with any desired degree of resistance against movement longi-V 4tudinally along the barAs. By sliding the plate H4 longitudinally of the bar A3 to different positions thereon the bellY may be sounded Aat different'points in 'the tra'vel of thepaper-l vcarriage, according tothe'length of the lines `which it is desiredto write.

the lug 0 4'is formed upon the rear end of al plateV P4, mounted to slide backward and forward upon the upper surface of the frame X.v

This plate P4 is provided upon its under side with Aa lug Q4, (shown in dotted lines inFig. 7,) which lug passes through and travels in a slotin the yframe X. Av coiled spring-R4,

will be carried under the hook or projection' on the upper end of the rod U4, so. thatthe latter will be locked from downward move#v ment, and` inasmuch as the lower end of said rod is secured tothe universalrod M3, vwhich iis depressed' by the operation of'any key-le-` A,

ver or of thespacingbanit follows that 'this locking of the rod U4 from downward movei ment serves to lock all of the keylevers and the spacing-bar fromoperation.

. Itwill be understood from theforegoing that .the locking device described serves to `an tomatically lock the `machine whenever the:

vlO

paper-carriage reaches a position in its movement to the left which causes the arm 14 to contact with the lug O4 and swing the rear end of the plate P4 beneath the projection or hook upon the upper end of the rod U4, and inasmuch as the plate which carries the arm I4 is adjustable longitudinally of the rackbar A5, as heretofore described, it follows that by adjusting said plate to different positions longitudinally of the rack-bar the locking mechanism may be set to lock themachine at any desired point in the travel of the paper-carriage. The machine may thus be readily adjusted for lines of any desired length within its capacity. The adjustment is readily effected by first setting the papercarriage to the desired position for the termination of the lines, as at 40 or 50 or G0, for instance, and then with the carriage in this position sliding the plate H4 along the rackbar A3 until the arm I4 contacts with the lug O4 on the plate P4 and presses the latter to the right to its limit of movement, Fig. 6. When this has been done, the paper-carriage may be returned to right-hand position for the beginning of the first line, and thereafter in the operation of the machine it will be arrested at each travel toward the left at the particular point determined by the setting of the locking mechanism in the manner above described.

For the purpose of readily withdrawing the plate P4 from beneath the projection upon the upper end of the rod U4, and thereby unlocking the machine to permit further operation of it and further movement of the papercarriage toward the left-as, for instance, where the machine becomes automatically locked in the middle of or near the end of a Word and it is desired to finish the word in that line-there is pivoted to the upper side of the frame X a lever S4, Fig. 7, whose lefthand end is connected to the forward end of the plate P4 and whose right-hand end eX- tends outwardly and forwardly to the side of the machine and is provided with a knob T4, by means of which the outer end of the lever may be readily pressed rearward by the operator whenever it is desired to permit extra operation of the machine beyond the lockingpoint, as for'the purpose above mentioned.

It will be observed that the plate or bar P4 is arranged to have motion about two independent parallel aXes-to wit, its pivotal connection with the lever S4 and the pivot of said lever S4 itself. The plate P4 is thus capable of a swinging motion about its pivotal connection with the said lever S4 and also of an independent endwise motion. A universal motion in a plane is thus provided for the stop or locking plate P4. The plate P4 is withdrawn from the path of the arm I4 by the rearward motion of thelever S4, and the spring R4 thereupon returns plate P4 to its normal position against the stop Q4.

The next feature of the machine to be described is the adjustable marginal stop for limiting the movement of the paper-carriage toward the right in resetting it for the beginningof a new line. As seen in Fig. 7, there are mounted upon the upper side of the frame X, beneath the right-hand end of the papercarriage, (when the latter is in the position shown in the drawings,) two parallel plates The rear one, A5, of these two plates is secured in fixed position upon the upper sido of the frame X, while the forward one, B5, is attached to the frame by means of bolts C5 passing through short longitudinal slots in the plate. The plate B5 has its rear edge formed into a rack, (or ratch,) with the teeth of which cooperates a latch D5, pivoted upon the upper side of a rectangular plate E5, conned between the plates A5 B5 and adapted to be slid longitudinally of them upon the up-` per surface of the frame X. The latch'D5 is provided with teeth similar to the teeth upon the plate B5 and adapted to coperate therewith and is pressed into engagement with the rack by a spring F5. The plate A5 is provided with a scale, as shown, with which cooperates a pointer D9 on the plate E5 to indicate the different positions of the plate longitudinally of the plates A5 The latch D5 is provided with a shoulder G5, which cooperates with the depending lower end of a plate H5, pivoted at its upper end between ears H5, formed upon the upper side of the bottom plate L oi the paper-carriage frame, Figs. 6, 7, and 14, the lower end of said plate depending through a longitudinal slot in said plate, as shown. The plate H5 is free to swin g in one direction-to the left-but is held from movement in the opposite direction by the stop H7, Fig. 14E. l/Vhen the paper-carriage is slid to the right in its resetting movement, the lower end of the plate H5 will contact with the shoulder G5 of the latch D5, thus arresting the papercarriage and limiting its movement in such direction. The plate E5 and latch D5 may be adjusted longitudinally of the plates A5 B5 and set in any desired position, according to the scale upon the plate A5, to produce the desired width of margin upon the left-hand side ofthe sheet of paper, as will be readily understood.

Under the arrangement of the stop devices above described the shock of arresting the paper-carriage at the end of its resetting movement is borne by the main frame of the machine, instead of being borne by some more delicate part ot' the machine, as is frequently the case.

For the purpose of throwing the stop devices above described out of operation whenever it is desired to move the paper-carriage to the right beyond the point for which the stop is set and to permit such movement of the carriage without disturbing the adjustment of the stop there is provided a releasing device consisting of a rod l5, whose lefthand end projects through the left-hand side frame N of the paper-carriage and is surrounded by a coiled spring confined between IOO IIO

the button upon the end of the rod and said side frame, Figs. 5, 6, and 7. The rod extends to the right longitudinally of the papercarriage to a point adjacent its middle, and at its extreme right-hand' end enters the slot or opening between the ears H5,between which the stop-plate H5, heretofore described, is pivoted, and is connected to said plate, Figs. 7 and 14. 'The coiled spring surrounding the rod l5 at its outer end yieldingly holds it in normal left-hand position; but when the rod is pressed inward its inner end will swing the plate H5 upward above the horizontal plane of the shoulder upon the latch D5, and thus while in this position permit the lower end of said plate to clear the shoulder on the latchplate when the paper-carriage is moved toward the right. By pressing the `left-hand end of the releasing-rod l5 inward at any resetting of the paper-carriage, therefore, the latter may be moved to extreme right-hand position or to any other desired position beyond the point at which the marginal stop may be set to arrest it.

K5 is an inking-ribbon wound at one end upon a spool L5 and at its opposite end upon a spool N5, said spools being suitably secured to the framework of the machine by means of arms M5.

O5 R5 are ratchet-wheels upon the spools L5 N5, and P5 S5 are pawls for operating said ratchet-wheels. The pawls P5 S5 are pivotally connected with arms U5 T5, pivoted at b to the frame of the machine and connected at their rear ends with the universal bar M5. The pawls are drawn toward the ratchets by springs V5.

Q5 is one of two detents for preventing backlash of the ribbon-spools, and the pawls and detents are alternately engaged with and disengaged from their respective ratchetwheels by a notched rock-shaft W5, having a handle X5.

Y5 Y5 Z5 Z5 are guide-rollers for the ribbon K5.

A5 is a curved vertical plate or frame secured at its lower end to the frame X, and B5 is a pointer which cooperates with the scale upon the plate W5, as shownin Fig. 1.

C5 represents ears connected with the plate A5, between which a rocking ribbon-carrier is pivoted.

D5 is a lower cross-bar or plate E5, with two vertical extending arms formed integral therewith, and F5 an upper plate .intermediate and integral with the upper ends of the arms E5 of the` said rocking ribbon-carrier frame. c represents ribbon-guiding ears on the said frame, and d represents guide-arms formed integral with the cross-bar D5.

G5 is an elongated opening or slot in the top plate F5 to permit the passage of the type on the bars.

l5 is a bracket secured to the frame X in front of the plate A5 and to which is pivoted a lever J5, and to the forward end of the le ver J5 is pivoted a link K5, also pivoted toia universal bar L5, underlying the key-levers A and forming part of a bail, whose side arms M5 extend rearwardly and are pivotally supported in the side frames of the machine.

N5 is a pin or screw passing through slots in the plates l5 and connected to the lower ends of two arms O5,.whose upper ends are pivoted to an arm P5, projecting forwardly from the cross-oar D5. A coiled spring Q5, connected to the bracket l5 and one of the rods O5, holds said rods downwardly. The lever J5 operates the pin N5 of the ribboncarrier in a manner more fully set forth in another divisional application, Serial No. 712,477, tiled AprillO, 1899. Hence the ribbon-operating mechanism neednot be described herein more in detail, since the same is fully described and claimed in said divisional application.
